Abstract
New fuel production alternatives are becoming increasingly necessary to replace fossil energy sources and reduce the environmental implications of carbon emissions. In this context, renewable sources, such as waste cooking oil (WCO), are an excellent choice for producing bio-based fuels. However, to use WCO as fuel, the oxygen content in its triglyceride structures must be removed. To this end, bimetallic Co-Mo and Ni-Mo supported on pristine carbon nanotubes (CNT) and oxidized carbon nanotubes (CNTox) were synthesized to investigate the hydroprocessing of WCO in a batch reactor operating at 350 °C, 70 bar of H2 (evaluated at ambient temperature) for 3 h. The results showed that Ni-Mo/CNTox exhibited superior catalytic performance, mainly producing n-alkanes in the range of C14-C22 with a carbon conversion of about 67 mol.% and being selective for light alkanes (6.6 mol.% of C5-C7), jet fuel (11.4 mol.% of C8-C16) and diesel fuel (81.2 mol.% of C17-C22). On the other hand, a residence time of 5 h was necessary to achieve the same results with the carbon-supported Co-Mo catalysts. Hydrodeoxygenation was the main deoxygenation route followed using CNT based catalysts.
期刊介绍：
Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processes, and biomass products for new renewable sources of energy and materials.
The scope of the journal extends to the environmental, management and economic aspects of biomass and bioenergy.
Key areas covered by the journal:
• Biomass: sources, energy crop production processes, genetic improvements, composition. Please note that research on these biomass subjects must be linked directly to bioenergy generation.
• Biological Residues: residues/rests from agricultural production, forestry and plantations (palm, sugar etc), processing industries, and municipal sources (MSW). Papers on the use of biomass residues through innovative processes/technological novelty and/or consideration of feedstock/system sustainability (or unsustainability) are welcomed. However waste treatment processes and pollution control or mitigation which are only tangentially related to bioenergy are not in the scope of the journal, as they are more suited to publications in the environmental arena. Papers that describe conventional waste streams (ie well described in existing literature) that do not empirically address ''new'' added value from the process are not suitable for submission to the journal.
• Bioenergy Processes: fermentations, thermochemical conversions, liquid and gaseous fuels, and petrochemical substitutes
• Bioenergy Utilization: direct combustion, gasification, electricity production, chemical processes, and by-product remediation
• Biomass and the Environment: carbon cycle, the net energy efficiency of bioenergy systems, assessment of sustainability, and biodiversity issues.
